Abstract
A cutting implement with an adjustable guide, such as a knife, includes a handle, an elongated blade, a guide adjustable with respect to the blade, and a knob substantially received in a cavity formed in the upper region of the handle. The knob protrudes from the cavity and cooperates with the guide so that a user can adjust the space between the guide and the blade by rotation of the knob.

- a handle;
- an elongated blade extending from one end of the handle;
- a guide adjustable with respect to the blade, the adjustable guide having a portion spaced apart from the blade;
- and
- a knob substantially received in, but protruding from, a cavity formed in an upper region of the handle, the knob cooperating with the guide for adjustment of the space between the guide and the blade, the knob being configured as a wheel having a pair of oppositely facing and spaced apart shoulders, and the cavity comprising a pair of spaced apart recessed surfaces formed substantially parallel to the blade, each of the surfaces guiding a respective one of the shoulders when the knob is received in the cavity.
